Metric bolts are referenced using "M" sizes, such as the M8 bolt size. The size of a metric bolt is specified using pitch, diameter, and length in millimeters. For example, in M8-1.0*20, the "M" means the Metric thread designation, the digit 8 refers to the Nominal diameter (in millimeters), 1.0 refers to the pitch, and 20 refers to the length.

To know the diameter, you need to refer to a gauge guide to match the gauge with a fraction of an inch. For example, a #0 gauge is 1/16 inch in diameter. A #1 gauge is 5/64 inch, and #2

Once you've identified which metric wrench you would use, look at the chart to locate its SAE counterpart. Now, we do realize that the chart doesn't look complete on the metric side. However, the only common wrench size that isn't included in the chart is 18 mm, and it's counterpart is 45/64″. If you don't have that size, don't worry—neither do we.

Metric Threads - Coarser Threads The table below indicates some of the most used coarse threads up to size M 68. Note that the ISO 724 standard specifies threads up to M 300. The table below is not complete. 1) For metric threads pitch is the distance between threads. 1 mm = 0.039 inches Metric Bolts - Proof Loads

The bolt body has three dimensions that are essential to any bolt size chart: bolt diameter and thread pitch. In standard bolt size charts, the thread pitch is the number of threads in one inch. In the metric system, it's the distance between two threads in millimeters. The thread pitch can be further classified as coarse, fine, and superfine.

To know the diameter, you need to refer to a gauge guide to match the gauge with a fraction of an inch. For example, a #0 gauge is 1/16 inch in diameter. A #1 gauge is 5/64 inch, and #2 gauge is 3/32 inch. Lastly, count the threads in one inch to get the thread spacing value.
